Today as I was playing as TEC rebels I captured the pirate planet. Since they were killed I figured I could use the planet and all the "friendly" turrets and ships stationed there as a good defense. However after I captured it, I repeatedly began hearing the pirate sounds, the one you hear when you discover the pirate planet. Since it wouldn't stop and the pirates were intent on attacking me, yet they couldn't because I was friendly with them I figured it must be a bug.
